While we are excited and anxiously awaiting the AGV PistaGP helmet, one American helmet manufacturer is less-than-thrilled with the Italian company’s latest offering: Del Rosario. A small boutique firm based out of New York, Del Rosario’s aim was to bring to market helmet designs that were “caught up to the rest of the industry.” Showing off a number of CAD renders since its inception, Del Rosario has clearly missed its late-2011 shipping date, and as far as we can tell, has not actually produced any physical prototypes or finished models.

Getting a fair bit of press and then falling off the radar, Del Rosario is back in the limelight as the company sent a worded warning to AGV through its corporate Facebook page. According to a message posted by Del Rosario on its social media portal, one of the company’s former advisors showed AGV Del Rosario’s stylebook, and now three years later the PistaGP has emerged with a shell design that has some obviously similar characteristics to Del Rosario’s renders.
